Alberto,
We stayed at the Fairfield Inn, International Cove. It was great, clean and safe. It was on Canada Ave. which is a short street and at the end of the street was the Wyndham Universal. It was 5 mins. tops to Universal. The rooms were big and it had a limited breakfast. They had a free shuttle to Universal for sure and I am not sure about the other parks. They had a lot of international visitors there so I would expect that they had shuttle busses to the other parks.
